GtkBuildable changes break GNOME Builder
In 4.8 we made it possible to reliably use various GtkBuilder API to merge multiple .ui
files into the same template context. Commit 92edd4c4 breaks this because you can no longer control the buildable-id
using GtkBuildable.get_buildable_id()
.
gnome-builder#1925 (closed) contains the breakage in Builder Nightly.
Reverting 92edd4c4 fixes the issue, which is probably what we should do in the meantime until something else can be resolved.
